Struct QuerySpec 

pub struct QuerySpec { /* private fields */ }

Spec for starting a query.

Implementations

impl QuerySpec

pub fn new(qname: Name, qtype: ResourceType) -> QuerySpec

Available on crate features alloc or no-atomic or std only.

Build a new spec for an mDNS query.

pub fn qname(&self) -> &Name

Available on crate features alloc or no-atomic or std only.

The query name.

pub const fn qtype(&self) -> ResourceType

Available on crate features alloc or no-atomic or std only.

The query resource type.

pub const fn qclass(&self) -> ResourceClass

Available on crate features alloc or no-atomic or std only.

The query class.

pub const fn unicast_response(&self) -> bool

Available on crate features alloc or no-atomic or std only.

Whether to request unicast responses (RFC 6762 §5.4).

pub const fn timeout(&self) -> Option<Duration>

Available on crate features alloc or no-atomic or std only.

The absolute timeout for the query, if set.

pub const fn max_answers(&self) -> Option<usize>

Available on crate features alloc or no-atomic or std only.

Maximum number of collected answers, if explicitly overridden.

When None the Query state machine uses its built-in default (256).

pub const fn with_qclass(self, v: ResourceClass) -> QuerySpec

Available on crate features alloc or no-atomic or std only.

Override the query class.

pub const fn with_unicast_response(self, v: bool) -> QuerySpec

Available on crate features alloc or no-atomic or std only.

Request unicast responses (RFC 6762 §5.4).

pub const fn with_timeout(self, v: Duration) -> QuerySpec

Available on crate features alloc or no-atomic or std only.

Set an absolute timeout for the query.

pub const fn with_max_answers(self, max: usize) -> QuerySpec

Available on crate features alloc or no-atomic or std only.

Override the maximum number of collected answers for this query.

When the pool reaches max, the oldest entry (FIFO) is evicted to make room. Setting max to 0 disables answer collection entirely.

Trait Implementations

impl Clone for QuerySpec

fn clone(&self) -> QuerySpec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for QuerySpec

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Eq for QuerySpec

impl PartialEq for QuerySpec

fn eq(&self, other: &QuerySpec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
